摘要:
The invention relates to a method for remote attestation. In the method is created a first asymmetric key pair in a trusted platform module in an electronic device. A first public key and software platform state information are certified with an attestation identity key associated with the trusted platform module to produce a first certificate. A second asymmetric key pair is produced in an application within the electronic device. The second public key is certified with said first secret key to produce a second certificate. A message is signed with the second secret key to provide a message signature in the first electronic device. The message and the message signature, software platform state information, the first certificate and the second certificate are sent to a second electronic device.

Methods and apparatus, including computer program products, are provided for credential transfer. In one aspect there is provided a method. The method may include receiving, at a first device, an authorization token; determining, at the first device, a delegation token, one or more credentials, and metadata; and providing, by the first device to a second device, the delegation token, the one or more credentials, and the metadata. Related apparatus, systems, methods, and articles are also described.

An apparatus for authentication of fragments using hash trees may include a processor. The processor may be configured to provide one or more data fragments and a hash tree representing the one or more fragments, send at least one first fragment accompanied by any nodes of the hash tree necessary to authenticate the one or more first sent fragments, and send one or more subsequent fragments accompanied by only some, but not all, of the nodes of the hash tree necessary to authenticate the one or more subsequent fragments with the other nodes that are not sent but are necessary for authentication having been previously sent in conjunction with a prior fragment.

The exemplary embodiments or the invention provide at least a method, apparatus, and program of computer instructions to perform operations including receiving a challenge from a prover device, reading and saving an old value of a selected platform configuration register, obtaining at least one measurement or property and forming a new platform configuration register value, where the forming includes calculating a cryptographic hash over the old value of the platform configuration register and the obtained at least one measurement or property, triggering, with the trusted software, an attestation by sending a challenge to a trusted platform module/mobile platform module, and sending by the prover device a device certificate, attestation, at least one measurement or property, and old platform configuration register value to the verifier. Further, the exemplary embodiments or the invention teach sending a challenge to a trusted software of a prover device, and receiving by the verifier device a device certificate, attestation, at least one measurement or property, and an old platform configuration register value from the prover device, checking by the verifier device that extending the old platform configuration register value with the at least one measurement or property results in a new platform configuration register value that has been attested, and using the new platform configuration register value in attestation of the prover device.
